What Our Clients Say
"We needed a React Native developer who could ship a high-quality fitness app on both iOS and Android simultaneously. Protechplanner placed someone who delivered a polished app with smooth animations and offline sync in 10 weeks. Our App Store rating is 4.8 stars and we have had zero critical crashes since launch."
Aarav Singh
Founder, FitTrack
"Finding an iOS developer who truly understands SwiftUI and Apple HIG compliance is difficult. Protechplanner found one on the first try. He delivered our e-commerce app with flawless navigation, proper haptic feedback, and Apple-approved in-app purchase implementation. Passed App Review first submission."
Lena Fischer
Product Manager, RetailApp
"We had 150,000 Android users on a legacy Java app that needed full Kotlin rewrite with Jetpack Compose. Protechplanner placed a senior Kotlin developer who completed the migration in 12 weeks — zero data loss, 60% reduction in crash rate, and our average session time increased 35%."
